Hi I am in the throws of purchasing a 1930s house that needs modernising. It largely looks sound but there are cracks along the edge of the ceiling and wall all along one side of one bedroom. Other rooms look okay although they are all wallpapered (all firm and intact) and have coving. I have attached 3 photos. I will get a building survey done to look but wondered if anything can be suspected from observation. Any thoughts appreciated. Thanks.

Look more to be plaster shrinkage and minor differential movement than anything structural.

Any photos of the outside of that area, as above its unlikely to be structural but the cracks also appear rather wide for drying/settlement cracking

Looks to me as if a previous issue has been plaster-boarded over. That is based on there being one big crack up and then along, probably on a board edge.

At the corner crack I suspect you might find a similar crack outside, so picture please as already mentioned.

 

Probably not big issues, poss workmanship from prev repair. But could be.

not uncommon in houses of that era for internal walls to be bricked straight onto floorboards. Have a look on youtube gosforth handyman he has exactly this issue. massive cracks as the wall was built on wood!
